SAFETY-RAZOR.

and its primary object is to provide a devicel of this character ofsimple and inexpensive construction in which the corners of therazor-blade as well as the cutting edges thereof are protected toprevent injury to the user'.

A further object of the invention is to provide -a safety-razor the artsof which may be en apart.

The construction of the improvement will be fully described hereinafterin connection with the accompanying drawings, which form part of thisspecification, andits novel features will be set4 forth in the appendedclaims.

In the drawings, Figure 1 is a view in perspective of a safety-razorembodying the invention. Fig. 2 is -a erspective view of therazor-shield detached Fig. 3 is a similar view ofthe blade. Fig.'4 is anelevation of the handle detached. Fig. 5 is a longitudinal section ofthe handle. Fig. 6 is a section on the line 6 6 ofFig. -1. Fig. 7 vis atransverse section on the line 7 7 of Fi 1; and 35 of teeth 2, thecentral tooth 3 of each row and and State of Pennsylvania, have i.Specification of Letters Patent.

being formed with a threaded opening 4 for a purpose hereinafterdescribed.

The central portion 5 of the shield is dee pressed, and its side ortions6 are oppositely curved, as best s own in Fig. 7. The shield is formedWith a central perforation 7 for the passage of the end of thesecuring-rod 8 of the handle. The upper surface of the shield 1 isprovided at each end,centrally of its Width, with a triangular lug 9 andat'each of its corners with a guard-flange 10, said flanges extendingalong both the end and side edges of the shield for a short distance andforming guards within which the corners of the blade fit. j Y

The end teeth '11 atV one edge of the shield Patented Jan. 22, 1907.

project beyond the adjacent teeth and are perforated to form bearingsfor a pintle 12, upon which is supported a tubular roller 13.

14 designates the razor-blade, curved in cross-section to conform to theshape of the shield and formed with central triangular y end notches 15to receive the lugs 9 of the shield. The corners of the blade fit withinthe corner guardflanges of the shield, and the connecting-rod 8 of thehandle extends through a threaded central opening 16 in the blade.

The handle 17 is hollow, as shown in Fig. 5, and is closed at its outerend by a knob 18, from which the connecting-rod 8 projects.

The knob, 18 is securedto the handle by a shield I provide at eitherside of the shield an adjusting-screw 20, said screws extend-A ingthrough the threaded openings 4 of the central teeth 3 of the shield.

It will be apparent that the blade '14 is firmly held against horizontalor transverse play by the corner-flanges and the triangular` lugs andnotches and also that the roller, which revolves freely upon itssupport, will facilitate the operation and manipulation of the razor. j

Having fully described my inventibn, what I claim as new, and desire tosecure by Letters Patent, is-

1. In safety-razors,.a shield and a blade having the same transversecurvature to conform to each other, teeth formed on the longitudinaledges'` of said shield, a guard formed on each corner-tooth to receivethe corners of said blade, the two corner-teeth of one llongitudinaledge heiligl extended beyond the remainder of the teeth of said edge, aroller journaled in said two projecting teeth, and end lugs carried bythe shield to 4engage in notches provided therefor in the IOO IIO

two corner or end teeth of one edge projecting? beyond the remainderofthe teeth of said edge, and a roller journaled in said two projectingteeth.

3. In safety-razors, a` shield member and a blade member transverselycurved in the same manner to conform to eac-h other, cen#trally-disposed end lugs carried by one member to engage in notchesformed in the other member, teeth formed on the longitudinal edges ofsaid shield member, the end teeth of one longitudinal edge beingextended beyond the remainder of the teeth on the same edge, a rollerjournaled in said extended teeth, and guard-anges carried by the endteeth of each edge to receive the corners of said blade member. l

4. In safety-razors, a transversely-curved shield having teeth on bothlongitudinal side edges and having the end teeth on one longitudinalside edge projecting beyond the remainder of the teeth `pn the sameedge, a

roller journaled in said two proj eoting teeth, and atransversely-curved blade fitting on the shield the blade and shieldhaving the same transverse curve, whereby the inner face of the bladecontacts throughout its surture to the shield and closely fitting onthel upper face thereof, and means for securing 7' the blade and shieldtogether.

In'testimony whereof I aHiX my signature in the presence of twowitnesses.
